Health effects of coffee

Coffee has many different effects on our health, and it can be both good and not so good for us. Most people can safely drink up to three or four cups of coffee each day. At these levels, coffee often helps our health more than it hurts it.

One big review in 2017 looked at many different studies and found that regular coffee drinking is usually safe. However, there are some exceptions. For example, women might have a slightly higher chance of breaking bones if they drink a lot of coffee. Also, women who are pregnant should be careful, as drinking too much coffee might increase the chance of losing the baby or having a baby who is smaller than usual.

But it’s important to remember that not all studies are perfect, and results can change depending on things like age, gender, and how much coffee someone drinks.

Health effects

A study from 2014 found that drinking coffee — about four cups a day — was linked to a lower chance of passing away from any cause, and also a lower chance of having heart problems. More studies agreed that drinking two to four cups of coffee each day was linked to a lower chance of dying from any disease.

Coffee does not cause stomach problems, but it might make some people feel the need to go to the bathroom soon after drinking it. Drinking coffee in moderation does not seem to increase the risk of heart disease. In fact, some studies show that drinking three to five cups of coffee a day might lower the chance of certain heart problems, especially for people who have already had serious heart issues. However, drinking more than five cups a day might increase the chance of heart problems.

Drinking coffee has also been linked to a lower chance of developing Parkinson's disease and type 2 diabetes. Some studies suggest coffee might help protect the liver and lower the risk of certain cancers, like cancer of the uterus and liver. Overall, drinking coffee seems to have many health benefits when enjoyed in moderation.

Mental health

The National Health Service suggests that cutting down on coffee might help lower feelings of worry. In people who already have mental health issues, caffeine, the main active ingredient in coffee, can make anxiety worse, especially in large amounts. Stopping caffeine can help reduce anxiety for some people.

Early research shows that drinking coffee might be linked to a lower chance of feeling very sad. Studies about whether coffee helps prevent memory loss and thinking problems in older adults are not clear because the research quality was not very good.
